It's pretty easy for paper to take over my office and studio, and even other rooms in the house. It comes in at the rate of about 15 pieces of snail mail per day, countless sales receipts, plus whatever e-mails or web pages I foolishly print. Resolved: if I can find the information easily on the internet, I do not need to store it in paper form in my house. If (as with magazine articles) I may want to refer to it later, it can be stored as a pdf on my computer. Resolved: Add as close as possible to zero paper files to my existing collection. Reduce the number of files in my house by one drawer each year, until I am down to... er... 4?
This will take some diligence. And some screening of existing files.
